My mother is an ISFP and she is way too nice. She does things no one ever asked her for. She protects the people that others are gossiping about. The can't stand it when people are joking about others. She's always concerned about what others are thinking of her. She's very self sacrificing. I find that behaviour extremely annoying. Whenever my mother complains about the fact that she's unhappy (she does it all the time), I explain to her that maybe she should act more like me and be more selfish, but she doesn't listen. So my question is: how could I make my mom behave less annoying and make her become happier?
